Combined toilet and seat apparatus

ABSTRACT

A combined toilet and seat apparatus, capable of being transformed from a flat-pack configuration for storage and/or transportation to a box-like configuration for use. The apparatus comprises front and rear panels connected by respective side panels, which side panels are capable of forming inwardly-angled side panels to thereby provide support to a top panel connected to either of the front and/or rear panel, the top panel forming a seating platform and a base panel connected to either of the front or rear panel. The top panel and/or the base panel comprises one or more interlocking portions for interlocking the top panel and/or the base panel with one or both side panels to thereby maintain the apparatus in the box-like configuration.

This invention relates to a combined toilet and seat apparatus capable of being transformed from a flat-pack configuration to a box-like, use configuration. Further, the invention relates to a blank for forming a combined toilet and seat apparatus and an assembled—for use—combined toilet and seat apparatus.

Portable toilets are well-known in the art. An example of a similar arrangement is shown in U.S. Pat. No. 6,047,414, which discloses a combination packable toilet and stool. The stool includes an interlockable structure of die-cut paperboard. As it will be understood by those skilled in the art, the arrangement disclosed in this US patent appears to suffer from stability, rigidity and strength problems, at least, towards the bottom of the stool, where the front, back and side panels of the combined toilet and stool rest on the ground, as these points are furthermost from interlocking portions provided at or around the seat portion. Further, as there is some distance between the interlocking portions and the ground, the front, back and side panels will be prone to lateral forces when in use—as the ground may be slightly uneven and the user may put more weight on some panels and not others—which can buckle those panels leading to the stool/toilet collapsing.

The solution provided to these problems is identified as providing a second front panel, providing a dual thickness front panel, in which the two front panels are interlocked together. However, although the disclosed combined toilet and stool is intended to be sat on by persons of varying weight and size, it is our understanding that the provision of a dual front panel does not provide much enhanced strength, rigidity or stability and, therefore, there is a need for an improved combined toilet and seat, as provided by the present invention.

It is an aim of the present invention to provide a combined toilet and stool that is stronger, has greater rigidity, and is more robust and stable than the prior art apparatus, and that is capable of receiving adults of practically all sizes and weights.

Accordingly, in a first aspect of the present invention, there is provided a combined toilet and seat apparatus, capable of being transformed from a flat-pack configuration for storage and/or transportation to a box-like configuration for use, the apparatus comprising:

front and rear panels connected by respective side panels, which side panels are capable of forming inwardly-angled side panels to thereby provide support to a top panel connected to either of the front and/or rear panel, the top panel forming a seating platform; and

a base panel connected to either of the front or rear panel;

wherein the top panel and/or the base panel comprises one or more interlocking portions for interlocking the top panel and/or the base panel with one or both side panels to thereby maintain the apparatus in the box-like configuration.

Advantageously, the arrangement of the present invention provides a combined toilet and seat having greater stability, strength and rigidity than prior art apparatus. In particular, providing a base-panel increases the surface area of the combined toilet and seat on the ground, which aids stability of the combined toilet and seat and provides a greater contact area with the ground, which spreads out more evenly the weight of a user. Obviously, this is a great advantage if the combined toilet and seat is to be used on soft ground as sinking in to the ground is prevented or minimised. Further, the base panel effectively holds in position the inwardly-angled side panels in the lower regions of the seat, minimising the instability of these parts in use, and maintains the angular separation of the front and/or rear panel. As the angular separation of the inwardly-angled side panel and the front or rear panel is, effectively, constant, the amount that the lower portions of the combined toilet and seat—which contact the ground—can move or be moved during use is reduced, the combined toilet and seat apparatus of the present invention is more secure and stable for a user. In particular, as the intended material of manufacture is cardboard, paperboard or the like, it is important that a user believes that the combined toilet and seat apparatus will take their weight, both from the point of view of confidence in using the apparatus and the effect that this confidence has on whether the user will purchase the product. Further, the interlock maintains the box-like configuration of the apparatus. A further advantage of the invention is that the base panel allows the inwardly-angled side panels to extend further than prior art devices inwardly towards the centre of the box-like structure. Accordingly, the inwardly-angled side walls, which acts as further supports for the top panels—which define the seating platform—make the device capable of receiving a much heavier person and operating without reduced stability. Naturally, the angle provided at an apex of the inwardly-angled side panels can be altered to suit the intended weight capacity of the apparatus. In a preferred embodiment, only the base panel comprises one or more interlocking portions for interlocking the base panel with one or both side panels. Further preferably, in this embodiment the top panel, and the opposed front or rear panel comprise corresponding interlocking portions which provide an interlock therebetween for maintaining separation of the front and rear panels. Accordingly, this preferred embodiment provides greater stability and minimises lateral movement of the side panels, front panel and/or rear panel as at least one interlock of respective portions is provided at the top and bottom of the side, front and/or rear panels by parts of the top panel and base panel interlocking with those panels.

In a second aspect, the invention provides one or more blanks for forming a combined toilet and seat apparatus comprising:

first, second, third and fourth consecutive panels and connection means therebetween, for forming a front panel, a first side panel, a rear panel and a second side panel, respectively, of the apparatus;

fifth and sixth panels, for forming a seating platform and a base, respectively, of the apparatus;

the fifth panel extends from either the first or third panel and the sixth panel extends from an opposite end of either the first or third panel, wherein, the fifth or sixth panel, and the second and/or fourth panels comprise corresponding interlocking portions for forming at least one interlock therebetween.

According to a third aspect of the present invention, there is provided an assembled combined toilet and seat apparatus having a box-like configuration, the apparatus comprising:

spaced-apart front and rear panels connected by inwardly-angled side panels;

a top panel connected to either of the front and/or rear panels and supported by the inwardly-angled side panels to form a seating platform;

a base panel connected to either of the front or rear panels;

wherein an interlock is provided by corresponding interlocking portions between at least one of the inwardly-angled side panels, and the top panel or the base panel, to maintain the apparatus in the box-like configuration.

In order that the invention may be fully disclosed, embodiments will now be described, by way of example only, with reference to the accompanying drawings, in which:

FIG. 1 is a perspective view of a combined toilet and seat apparatus of the present invention;

FIG. 2 is a plan-view of a first partial blank for forming the apparatus of FIG. 1;

FIG. 3 is a plan-view of a second partial blank for forming the apparatus of FIG. 1; and

FIG. 4 is a partially-constructed combined toilet and seat apparatus of the present invention, showing the blanks of FIGS. 1 and 2 combined.

All Figures, and in particular FIG. 1, show a combined toilet and seat apparatus of the present invention, which toilet and seat is indicated, in general, by reference 1. The apparatus 1 includes a lid 2, a seating portion 3, a front panel 4, side panels 5,9, a rear panel 8 and a base panel 6. A toilet hole 7 is provided in a centre of the seating portion 3 and shows an inside of the apparatus 1. Through the toilet hole 7 can be seen inner surfaces of the rear panel 8 and the second side panel 9. The lid 2 is pivotally movable between the upper position shown in FIG. 1 and a lowered position when it can cover the seating portion 3. Naturally, the lid 2 is also movable in an opposite direction for when the apparatus 1 is in use as a toilet. When the lid 2 is lowered to cover the seating portion 3, an external surface thereof forms a external seating portion or seating platform. Of course, an in use of the toilet seating platform is provided by the seating portion 3 alone. The base panel 6 includes a tab 10 having slots 11 cut therein for receiving corresponding portions of the side panels 5,9, the corresponding portions on the side panels 5,9 later identified by reference 18. An interlock is provided between those corresponding interlocking portions 11,18.

FIG. 2, in particular, shows a first partial blank for forming into the combined toilet and seat apparatus 1 of the present invention. In particular, the blank of FIG. 2 is connectable to the blank of FIG. 3 before being assembled into the combined toilet and seat apparatus of the present invention. FIG. 2 shows in a centre of the cruciform-shaped blank the rear wall 8 of the combined toilet and seat. Extending upwardly from the centre is the base panel 6 and tab 10. In FIG. 2, the slots 11 in the tab 10 can be more clearly seen. Extending in an opposite direction to the base panel 6 from the rear panel 8 is the top panel 3′, which forms a first top panel located beneath the seating portion 3 shown in FIG. 1. Accordingly, a dual-layer seating platform is provided for when the apparatus is used as a toilet. The top panel 3′ has two tabs 12 which are locatable within two slots 13 provided on the blank of FIG. 3, and an interlock is provided between those corresponding interlocking portions 12,13. Extending to the left of the rear panel 8 is a first part 9A of the second side panel 9. The first part 9A is provided with a tab 14, at a far-edge, which is connectable with the second part 9B of the second side panel 9—shown in FIG. 3. A cut-out 18 from the panel 9A forms a slot 18—when assembled—for interacting with one of the slots 11. On the opposite side of the rear panel 8 is provided a first part 5A of the first side panel 5. At a far-edge of the first panel 5A is provided a tab 17, for connecting with the second part 5B of the first side panel 5—shown in FIG. 3. A cut-out 18 from the panel 5A forms a slot 18—when assembled—for interacting with one of the slots 11.

As can be seen in FIG. 3, in particular, a front panel 4 is provided in the middle of a crossbar region of this inverted T-shaped blank. To the left of the front panel 4 is provided the second part 9B of the second side panel 9. To a right of the front panel 4 is provided the second part 5B of the first side panel 5. Directly above the front panel 4 is provided the seating portion 3, as shown in FIG. 1, and the lid 2 is operably connected to the seating portion 3. Both the seating portion 3 and the top panel 3′ are provided with the toilet hole 7 in a centre thereof. An additional cut-out portion 20 is also provided to be optionally removed by a male user to aid use of the combined toilet and seat apparatus with male anatomy.

As can be seen in FIGS. 2 and 3, respective panels of the blanks are separated by scoring or perforated lines, so that the panels can be folded to form a box-like configuration and a flat-pack configuration. Scoring is shown in FIGS. 2 and 3 by alternate dot-dash lines 15 and double scoring 15 is provided, at least, between the seating portion 3 and the lid 2, to enable the lid 2 to be folded-back upon itself and rest over the seating portion 3, when the toilet is not in use or used as a seat. Further, double perforated lines indicated with reference 16 are provided between, at least, the front panel 4 and second parts 9B,5B of the second and first side panels 9,5. Additionally, the same arrangement is provided between the rear panel 8 and the first and second parts 9A,5A of the of the second and first side panels 9,5. In particular, the double perforations 16 (and the double scored lines 15) aid folding of the respective parts of the blanks. Additionally, double scoring 15 and double perforations 16 allow the blanks to lie flat and take a square-shape no wider than the size of the lid in either direction. Accordingly, in a folded, flat-pack state, the apparatus is advantageously stackable.

A unitary blank for making a combined toilet and seat apparatus of the present invention is provided by sealing the tabs 14 and 15 of the first parts 9A,5A to inside edges of the second parts 9B and 5B. The sealing is provided in the region of the apex of the inwardly-angled side panels 5,9. Preferably, glue is used to join the first and second parts 9A,9B of the second side panel 9 and the first and second parts 5A,5B of the first side panel 5. Even in this partly assembled state, the combined toilet and seat is unassembled and is still flat-packable for storage and transportation, and has an approximate square shape when folded up. In particular, the flat-pack nature of the device at this stage is provided by the double scored lines 15 and double perforated lines 16.

FIG. 4 shows the blanks of FIGS. 2 and 3 combined after sealing of the first and second parts 9A,9B and 5A,5B, connected using the tabs 14 and 17. FIG. 4 shows a combined toilet and seat of the present invention that has been opened up from its flat-pack state and the base portion 6 has been placed underneath the side panels 5,9, in particular, underneath the first parts 5A,9A. The tab 10 is shown at 90° to the base portion 6 and extends upwardly towards, and engages, the side panels 5,9, at the slot 18, provided in the region of the join along the perforation 16 between first part 5A and tab 17 and first part 9A and tab 14. The slots 11 provided in the tab 10 have engaged with the corresponding slots 18 and formed an interlock. As it can be seen in FIG. 4, the angular separation of the first portion 5A and the rear panel 8 is maintained by the interlocking nature of the slots 11,18 of the tab 10 and first parts 5A and 9A of the first and second side panels 5,9. Further, the interlock maintains the box-like configuration of the apparatus. In particular, this arrangement provides a great deal of strength, rigidity and stability to the combined toilet and seat apparatus. In order to assemble the combined toilet and seat apparatus shown in FIG. 1, the top panel 3′ is brought to rest upon the supports provided by the side panels 5,9 and the tabs 12 are located within the slots 13. The seating portion 3 is then brought over the top of the top panel 3′ and rests upon that panel 3′ forming a dual-layered seating platform for use when the apparatus is used as a toilet, and when the lid 2 is open. As mentioned previously, the lid 2 can be folded-back upon the seating portion 3 to close off the toilet, making a three-layered top panel. Slits 19 are formed in the seating portion 3 and the top panel 3′ for receiving handles of, for example, a carrier bag, which can be used as a collector or bowl for the toilet. In particular, the location of the slits 19 on opposite sides of the toilet hole 7 and the spatial arrangement of the slits keep the bag from closing upon itself whilst in use.

The combined toilet and seat apparatus of the present invention is manufactured from two pieces of cardboard, although it may also be manufactured from a plastics material, in an alternative embodiment. Further, the cardboard, paperboard or plastics material may have a corrugated construction. Preferably, the cardboard is biodegradable. Although the invention is described as including two tabs 14,17 for connecting the two pieces of cardboard together, the blank of the present invention could be formed from only one piece of cardboard and, therefore, in that situation, only one tab would be required to connect ends of the blank together to form the flat-pack version of the invention.
